About Force

Force is a push or pull acting on an object. The newton (N) is the SI unit — defined as the force needed to accelerate 1 kg at 1 m/s².

Pound-force (lbf) is common in the US; kilogram-force (kgf) is often used informally to express the weight of an object in everyday contexts.

Newton's second law: F = ma. A 1 kg object in Earth's gravity exerts ≈ 9.81 N (1 kgf) of force.

Torque = Force × distance. To convert force units for torque calculations, always convert to newtons first.
